Khangela ivalve: I-valve yokujonga nayo yaziwa ngokuba yi-valve yendlela enye okanye i-valve yokukhangela, umsebenzi wayo kukuthintela i-medium kumbhobho wokubuyela umva.Ivalve esezantsi yempompo yokuvala amanzi ikwayeyodidi lwevalvu engabuyiyo.Ivalve evula okanye ivale ngokwayo ngokuhamba kunye nokunyanzeliswa kwe-medium ukukhusela i-medium ekubuyeni ngasemva ibizwa ngokuba yi-valve yokukhangela.Iivalvu zokukhangela zezodidi lweevalvu ezizenzekelayo.Iivalvu zokukhangela zisetyenziswa ikakhulu kwimibhobho apho i-medium ihamba kwicala elinye, kwaye ivumela kuphela i-medium ukuba ihambe kwicala elinye ukukhusela iingozi.Ngokwesakhiwo sevalve yokutshekisha, inokwahlulwa ibe ziindidi ezintathu: ivalve yokuphakamisa, ivalve yokukhangela i-swing kunye nevalve yokukhangela ibhabhathane.Iivalve zokujonga ukuphakamisa zinokwahlulwa zibe ziindidi ezimbini: iivalve zokujonga ezithe nkqo kunye neevalvu zokujonga ezithe tye.Iivalve zokujonga i-Swing zahlulwe zaba ziindidi ezintathu: ivalve yokukhangela igqabi elinye, ivalve yokukhangela esebenza kabini kunye nevalve yokukhangela amagqabi amaninzi.Ivalve yokukhangela ibhabhathane yivalve yokujonga ngqo.Iivalve zokutshekisha ezikhankanywe ngasentla zinokwahlulwa zibe ziindidi ezintathu kwifom yoqhagamshelo: ivalve yokukhangela enentambo, ivalve yokukhangela eneflanged kunye nevalve yokukhangela edityanisiweyo.
Ukufakwa kwe-valve yokukhangela kufuneka kuhlawulele oku kulandelayo: Musa ukwenza ukuba i-valve yokukhangela ibhere ubunzima kumbhobho, kwaye i-valve yokukhangela enkulu kufuneka ixhaswe ngokuzimeleyo ukwenzela ukuba ingachaphazeleki ngoxinzelelo olwenziwa yinkqubo yokubhobhoza.
Xa ufaka, nikela ingqalelo kwindlela yokuhamba okuphakathi kufuneka ihambelane nesalathiso sotolo oluvotelwe ngumzimba wevalvu.
Ivalve yokukhangela ethe nkqo yohlobo lokuphakamisa kufuneka ifakwe kumbhobho othe nkqo.Ivalve yokukhangela i-flap yohlobo lokuphakamisa kufuneka ifakwe kumbhobho othe tye.
Iiparamitha eziphambili zentsebenzo ye-valve yokukhangela: Uxinzelelo lwegama okanye izinga loxinzelelo: PN1.0-16.0MPa, ANSI CLASS1 50-900, JIS 10-20K, i-diameter ye-nominal okanye i-caliber: DN15-900.
I-NPS 1/4-36, indlela yokudibanisa: i-flange, i-welding ye-butt, intambo, i-socket welding, njl., ubushushu obusebenzayo: -196℃-540℃, imathiriyeli yomzimba wevalvu: WCB.
ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (3041), CF8M (316), CF3M (316L), Ti, khetha izinto ezahlukeneyo, iivalvu itshekhi ingasetyenziselwa amanzi, umphunga, ioli, nitric acid, acetic acid, oxidation ngokwesondo. imidiya, urea kunye nezinye imidiya.
